Definitions

  • the invention relates to a support beam in a coating system for coating a web of paper or cardboard.
  • DE-OS 39 25 517 discloses a support beam for coating systems which by pressure elements arranged parallel to its longitudinal axis, in the form of pressure hoses or pressure cylinders, can be bent along its longitudinal axis in order to thereby adjust a specific course of its longitudinal axis. This also for reason of compensating for external forces which act upon the support beam.
  • the problem underlying the invention is to simplify the structure of a support beam which is adjustable in its flexure.
  • the present invention provides a support beam which is laterally adjustable along its longitudinal axis, and which has a more simplified structure than heretofore known.
  • the invention comprises, in one form thereof, a support beam used in a coating system for coating a web of paper or cardboard.
  • the coating system includes a roll for carrying the web.
  • the support beam has a length about the same as the roll and defines a longitudinal axis extending through the centroid of the support beam.
  • the support beam includes a plurality of cross-sectional surfaces disposed generally orthogonal to the longitudinal axis, and a plurality of rods distributed around the periphery of the support beam.
  • the rods are disposed a distance of at least 50 mm from the longitudinal axis.
  • At least one device is provided for applying a tension or compression force to at least one of the rods.
  • FIG. 1 is a cross section of the support beam according to an embodiment of the invention
  • FIG. 2 is an enlarged section of FIG. 1;
  • FIG. 3 is a perspective view of the support beam, doctor blade, and roll.
  • FIG. 4 is a sectional view of another embodiment of the support beam arrangement in the coating system.
  • the support beam 1 is coordinated with a roll 10 carrying, e.g., the web; it supports in this case a holding device 12 for a doctor blade 13.
  • the latter also is known as a dosing slat.
  • tie rods 2, 2' and so forth provided which can be tightened, each, by a piston 5 (FIG. 2) of a traction unit 4, 4', 4" and 4'".
  • Pressure chambers 16 are formed externally of end plates 15 of the support beam. These pressure chambers receive a preferably hydraulic pressure medium through lines not illustrated here. The pressure medium, of course, may also be compressed air.
  • the tie rods are in this case preferably screwed into an opposite end plate 15 of the support beam so as to enable an easy exchange.
  • thrust rods i.e., if the tie rods used here were used as thrust rods, it would be much more expensive to provide the respective pressure chambers for the hydraulic or pneumatic pressure medium. Furthermore, the thrust rods would then need to be secured, or supported, against deflection at points distributed uniformly across their entire length.
  • the guide plate 18 which features guide holes fitting exactly the thrust rods 2'. A plurality of such plates 18 would be provided.
  • the pressure chamber is referenced 16'.
  • tie rods 2 could be tightened by means of threaded nuts and threading (not shown).
  • tie rods or thrust rods
  • These are then to be arranged at a preferably symmetric distribution across the cross section of the support beam-cross section perpendicular to its longitudinal axis. To a certain extent, it is also possible to deviate from the perfectly symmetric arrangement.
